Abstract
The invention discloses the belt gear of a kind of variable gear ratio, belong to belt gear field.It includes rotating shaft, trapezoidal revolving body, draw-in groove, belt.Belt sleeve is on two revolving bodies, and is fixed by draw-in groove.Driven by motor screw motion, makes draw-in groove produce displacement, allows belt position change, adjust and transmit ratio, reach the effect of speed change.The present invention has simple in construction, it is easy to accomplish, it is not necessary to complicated equipment, as long as making belt sleeve can be achieved with speed change on revolving body.
Description
Technical field
The present invention relates to a kind of belt gear, be specifically related to the belt gear of a kind of variable gear ratio.
Background technology
Existing gear-shift mechanism, the number of teeth is constant, and speed change to be realized needs the gear of a lot of different numbers of teeth, thus needs the equipment that comparison is heavy and complicated.And current mechanical continuously-variable transmission structure is the most complicated, and transmission efficiency is relatively low.
Summary of the invention
It is an object of the invention to provide the belt gear of the variable gear ratio of a kind of simple in construction.
A kind of belt gear of variable gear ratio, it is characterised in that: it is made up of drive mechanism and governor motion；Above-mentioned drive mechanism by the first rotating shaft, the second rotating shaft, be installed on the first trapezoidal revolving body of rotating shaft of the first rotating shaft, the second trapezoidal revolving body of rotating shaft being installed on the second rotating shaft, the first belt of being installed on the first trapezoidal revolving body of rotating shaft and the trapezoidal revolving body of the second rotating shaft form；It is axially moveable by belt, and two revolving body surface radius change of belt contacts, thus realizes the change of gear ratio.Above-mentioned governor motion includes the screw rod that motor pulley, screw pulley, the second belt being installed on motor pulley and screw pulley, the motor and the screw pulley that are connected with motor pulley are fixedly linked；Above-mentioned screw rod is threaded connection mode and is provided with belt draw-in groove；Above-mentioned first belt is positioned in belt draw-in groove.
Driven by motor screw motion in the present invention, makes draw-in groove produce displacement, allows belt position change, adjust and transmit ratio, reach the effect of speed change.The present invention has simple in construction, it is easy to accomplish, it is not necessary to complicated equipment, as long as making belt sleeve can be achieved with speed change on revolving body.
Above-mentioned belt draw-in groove includes a pair draw-in groove lamellar body and the draw-in groove boss between draw-in groove lamellar body；The most each draw-in groove lamellar body inwall is all provided with draw-in groove cylinder by draw-in groove cylinder fixing device.Draw-in groove moves to touch and makes belt move, between will produce friction, belt is easy for abrasion, and designed draw-in groove cylinder can move with belt and rotates, so that it may the inefficacy that avoiding weares and teares brings.
